Ibiharuro biri kurandurwa burundu HCFC-22 mu nganda zo mu kirere
2022-01-04
Uruganda rukora ibikoresho byo murugo rwakuyeho firigo ya R22 mukubara Nk’uko amasezerano ya Montreal abivuga, firigo ya R22 yahagaritswe mu bihugu byateye imbere kandi irashobora gukorerwa mu bihugu biri mu nzira y'amajyambere, ariko igihe cyo kuyikoresha no kuyikoresha ni 2030. Ku ya 26 Mutarama 2021, Minisiteri y’ibidukikije n’ibidukikije yasohoye Itangazo ku itangwa ry’umusaruro wa 2021 w’umusaruro, imikoreshereze no gutumiza mu mahanga ibicuruzwa biva mu mahanga bya Ozone (nyuma bikitwa Amatangazo). Dukurikije Itegeko rya Repubulika y’Ubushinwa ryerekeye gukumira no kurwanya ihumana ry’ikirere, Amabwiriza agenga imicungire y’ibintu byangiza urwego rwa Ozone n’izindi ngingo zibishinzwe, ibigo 20 bizatangwa hamwe na kota y’umusaruro wa toni 292.795 za hydrochlorofluorocarbone ( HCFC) mu 2021, hamwe na 46 bizatangwa hamwe na kota yo gukoresha toni 31.726 za hydrochlorofluorocarbone muri 2021. Ugereranije na 2020, igipimo cy'umusaruro wa hydrochlorofluorocarbone (HCFCS) harimo na HCFC-22 ntikizahinduka mu 2021, mu gihe igipimo cyo gukoresha kizagabanuka ku buryo bugaragara, bikarushaho gukuraho HCFCS mu nganda zikoresha ibikoresho byo mu rugo mu Bushinwa. Igipimo cy’umusaruro wa HCFC kirimo (HCFC) kizatangwa kuri hCFC-141B, HCFC-142B, HCFC-22, HCFC-123, HCFC-124 na HCFC-133A. Muri byo, HCFC-141B ni agent ifuro ikoreshwa mu nganda zikonjesha no gushyushya amazi. Nkuko gahunda yo kubira ifuro mu nganda za firigo yazamuwe kugeza kuri HFC-245FA + cyclopentane ifuro, kandi ku ya 1 Mutarama 2019, inganda zishyushya amazi zabujije burundu ikoreshwa rya HCFC-141B. Hcfc-141b yakoreshejwe gake kandi mike mubikorwa byo murugo. Igiteranyo cy'umusaruro rusange wa hCFC-141B muri 2021 ni toni 50.878, ntigihinduka kuva 2020. Ugereranije na cota y’umusaruro wa HCFC-22, umubare rusange w’ikoreshwa rya hCFC-22 mu nganda zoguhumeka mu 2021 ni toni 31.726, igabanuka rya toni 3,489 kuva kuri toni 35.215 muri 2020. Ibi bifitanye isano rya bugufi na firigo ya firigo muri inganda zo mu rugo. Umugabane w’isoko rya HCFC-22 ibyuma bifata ibyuma bikonjesha mu nganda zo mu kirere byari hafi 20% muri 2019, kandi uyu mubare uzakomeza kugabanuka muri 2020. Inganda z’ubukonje bw’imbere mu Bushinwa zimaze kugera ku ntera ishimishije mu guhagarika HCFC-22. Ingamba zo gucunga icyiciro cya HCFC-22 mu nganda zikoresha mu kirere mu Bushinwa kuva mu 2021 kugeza mu wa 2026 zemejwe na Komite Nyobozi y’ikigega cy’ibihugu byinshi, kandi yiyemeje gukuraho 70% by’ibicuruzwa bya HCFC-22 bitarenze 2026, aribyo birarenze kubisabwa na gahunda ya Montreal Protocole kugirango ugere kuri hCFC-22 kugabanuka. Tuzatanga umusanzu munini mu Bushinwa gushyira mu bikorwa amasezerano ya Montreal.
